Parameter
You can also set the maximum thread count in ColdFusion Administrator. Click Server Settings > Settings and specify the number of threads in Default Maximum Thread Count For Parallel Functions.
Description
Determines if all values of a struct satisfy a given condition.
Returns
True if all values match a condition; false, otherwise.
Syntax
structEvery(struct, closure [, parallel] [, maxThreadCount])
Member function
structObj.Every(callback)
History
ColdFusion (2021 release): Introduced the following parameters:
- parallel
- maxThreadCount
ColdFusion (2018 release) Update 5: Added this function.
Parameters
|
Required/Optional |
Description |
---|---|---|
struct |
Required |
Struct in which all values are to be searched. |
callback |
Required |
Function that encapsulates the criteria. |
parallel |
Optional |
True if you want to enable parallel programming. |
maxThreadCount |
Optional |
The number of threads the function can execute. The number of threads must be between 1-50. If the value exceeds 50, there is an exception. |
Example
Example 1
<cfscript> mystruct = {a=1,b=2,c=3}; doesValExist=(key,value,struct)=>return value!=1 writeoutput(structEvery(mystruct,doesValExist)) // Returns False </cfscript>
Output
NO
Example 2
<cfscript> structEven={a=2,b=4,c=8,d=10,e=12} isEven=(key,value)=>return value%2==0 writeOutput(StructEvery(structEven,isEven)) // Returns True </cfscript>
Output
YES
Member function
<cfscript> structEven={a=2,b=4,c=8,d=10,e=12} isEven=(key,value)=>return value%2==0 writeOutput(structEven.Every(isEven)) // Returns True </cfscript>
Example 3 - Named parameters
<cfscript> mystruct={"key1":"aval","key2":"aval1","key3":"aval2"} result=StructEvery(struct=mystruct,callback=function(key,val){ if (val.startswith("a")) return 1 else return 0 } ) writeOutput(result) </cfscript>
Output
YES
Arrow function
<cfscript> ordstruct=["key1":"abc","key2":"def","key3":"sss"] lambdaFunc= key => key.contains("key") writeoutput(ordstruct.Every(lambdaFunc)) </cfscript>
Output
YES
Using parallelization
<cfscript> mystruct= Structnew("ordered"); for(i=1;i<=10000;i++){ mystruct.insert("key#i#","val#i#") } function callback(key,val){ if(isObject(val)) return false return true } writeoutput(mystruct.some(callback,false)) writeoutput(structsome(struct=mystruct,callback=callback,parallel=true,maxthreadcount=10)) writeoutput(structsome(struct=mystruct,callback=callback,parallel=true)) try{ writeoutput(structsome(struct=mystruct,callback=callback,parallel=true,maxthreadcount=-10))} catch(any e){ writeoutput("<br>Type: " & e.type & " Message:" & e.message ) } try{ writeoutput(structsome(struct=mystruct,callback=callback,parallel=true,maxthreadcount=100))} catch(any e){ writeoutput("<br>Type: " & e.type & " Message:" & e.message ) } </cfscript>
